BRAKEI SPECIFICAIION forming part of Letcers Patent No. 608,561, dated August 2, 1898.

4 Application filecl Scptember 16, 1897. Serial No. 651,934. (No model.)

to which it appertains to maire and use the same, refcrence being had to the accompanying drawings, and to,the letters of reference marked thereon, whichform a part of this specification.

My invention relates to an improVed brake for vehicles of all kinds, especialiy street and steam-railway cars, and also to hoisting machinery and the like, the object of the invention being the production of a simple, durable, and quickly and positively acting brake that can be operated by mannal or other power.

The invention will first be described in connection With the accompanyng drawings and then pointed out in the claims.

Figure 1 of the drawings is a perspective view, partly in elevation, of my improved brake as applied to a car-wheel. Fig.'2 is a horizontal sectional view taken on the dotted lime A, Fig. 1.

Referring to the drawings, A designates a wheel to whichit is desired to apply a brake.

B represents the base of myimproved brake, which is fixed immovable in any suitable manner and arranged to stand in line With the tread of the wheel. That side of the base toward the wheel, which I term the face, s inclined inward from its top to its bottom.

II represents a brake-shoe placed between the base and the wheel and supported in any manner that Will allow it to be moved to and I have represented it as connected With and thns supported by the base through the medinm of arms I, projecting from the latter on either side, these arme being provided With inwardly-projecting stnds J which freely enter slots K, formed in the sides of the shoe, as clearly shown in Fig. 2. This arrangement permits the shoe to be moved forward toward or backward from the wheel.

C represents a cufleal block, Which I term the wedge. 7 It is located between the base and the shoe and may be both lowered and raised in that position by any suitable means.

One very desirable form of wedge-operating mechanism is shown in Fig. 1, wherein F is an operating-lever pivoted to a suitable support F; G, a bell-crank; G, a rodpivotaliy connecting one arm of the bell-crank to the operating-lever, and G a link pivotally connecting the other ar1n of the bellcrank t0 a boit G, secured to the wedge.

. The operation of my improved brake will be obvious fromthe drawings, as it will be readily understood that by moving the operating-lever in one direction the Wedge will be moved downward between the base and shoe, thus forcing the latter against the wheel With a braking action, and also that by moving the lever in the Opposite direction the wedge Will be raised, thereby perinitting the shoe to clear the wheel. c

Having thus described my invention,what I claim as new, and desire to secnre by Letters Patent, is" 7 1. In a brake, the combination, With a fixed base having an inclined face, of a brake-shoe movably supported in operative position relative to the base and thewheel or other article on which it is to act,a wedge interposed loosely between the inclined face of the base and the shoe, and rneans positively attached to the wedge for moving the latter into and out of wedging contact With the shoe.

2. In a brake, the combination, With a fixed base provided on its sides With forwardly-projecting arms carrying inwardly-projecting stnds, of a brake-shoe located between said arms and formed with slots for the reception of said studs, a wedge interposed loosely between the base and shoe, and 1neans formoving the Wedge into and out of wedging contact With the shoe.

3. A brake mechanism comprising a fixed base having an inclined face and provided With forwardly-projecting arms carrying i11- wardly-projecting stnds, a brake-shoe located between said arrns and formed with slots for receiving said studs, a wedge interposed loosely between the inclined face of the base and the shoe, and lever mechanism for moving the wedge into and out of wedging contact With the shoe.

In testimony whereof I affix my signature in presence of two witnesses.
